ComNet CNGE28FX4TX24MS: Ethernet Switch, 28 Ports: 24 x Gigabit Electrical Ports, 4 x Gigabit Fibre SFP Ports, Managed

The ComNet CNGE28FX4TX24MS Layer 2 managed 28 port Ethernet switch supports twenty-four  10/100/1000BASE-TX ports and four 1000BASEFX ports of Ethernet data. The four 1000BASE-FX ports are SFP configurable for fibre type (multimode or singlemode), connector type and distance. The exclusive C-Ring redundant ring feature protects networks from interruptions or temporary malfunctions with its fast recovery technology. The electrical ports support the 10/100/1000 Mbps Ethernet IEEE 802.3 protocol, and autonegotiating and auto-MDI/MDIX features are included. The CNGE28FX4TX24MS are optically (1000BASE-FX) and electrically compatible with any IEEE 802.3 compliant Ethernet device.
